Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for suturing a body canal such as the rectum, and is designed to minimize the portion that is not sutured when suturing the body canal with a stapler-like suture needle. This is what I did.

Conventionally, this type of suturing device in which the needle seat portion of the beak body is flattened has been proposed, but in this case, at both ends of the beak body outside the flat needle seat portion, It is difficult to provide a needle seat and a suture body for compressing the suture needle on the needle seat, resulting in some parts not being sutured during surgery.

In addition, when the needle seat part of the beak is made into a curved surface like a cylinder and the needle seat is provided here to minimize cuts, the suppressor that presses the suture needle will be perpendicular to the surface of the needle seat. Therefore, the plurality of pressing bodies are arranged radially with respect to the cylindrical needle seat part. Therefore, when a plurality of pressing bodies are accommodated in one suture body, each pressing body As the needle moves away from the needle seat while being held in the body, the distance between the pressing bodies increases, so that the pressing body and each pressing body compress a plurality of pressing bodies together on one suture body. During this time, it is necessary to cause slippage in the direction transverse to the direction of compression, resulting in a complicated structure and troublesome operation.

The present invention has been made in view of the above, and an embodiment of the present invention will be described below with reference to the drawings. For example, a cross-sectional view of the distal end 2 of the beak 1 that can be inserted into a duct in the body to be sutured, such as the rectum. The beak body 1 has a cylindrical shape, and the outer circumferential wall behind the tip 2 is a polygon of triangular or larger shape, and the rear part of the beak body 1 is a polygon of triangular or larger, and the outer circumferential wall of the polygonal portion has a large number of needle receiving seats. 3 are arranged in a row so as to reach near the corners of the polygonal part.

In addition, a base rod 4 is extended behind the beak body 1, and this base rod 4 includes:
Lever-shaped operating rods 5, the number of which corresponds to the shape of the polygonal part;
For example, if the polygonal portion is square as shown in the figure, four actuating rods 5 are pivotally mounted on fulcrums provided on the circumference of the base rod 4 so as to be able to swing in the radial direction of the base rod 4.

A suture body 6 is fixed to the tip of each of the four operating rods 5, and the suture body 6 is attached to a suture needle 1 in the form of a stapler.
1 are housed in the housing parts 7 facing the needle catch seats 3, and a guide part 9 in which a suppressor 8 for pushing out the suture needle 11 in the direction of the needle catch seats 3 is slidably housed is arranged side by side. It is something that is established and then removed.

Then, by moving the actuating body 21 slidably housed in the base rod 4 to the rear of the base rod 4, the rear end of each actuating rod 5 is pushed up toward the outside of the base rod 4, thereby connecting the suture body 6 and the needle. The intracorporeal duct to be sutured is sandwiched between the receiving seat 3 and the receiving seat 3.

Furthermore, a compression body 10 is fixed to the top of the pressing body 8, which is placed horizontally on a plurality of compression bodies 8 so that the plurality of compression bodies 8 can be compressed at the same time.

In the figure, reference numeral 12 denotes a stop pin that is inserted into the long groove hole 13 of the suppressor 8 and fixed to the suture body 6 to prevent the suppressor 8 from being pulled out from the suture body 6, and 14 is provided on the circumference of the base rod 4. operating rod 5
The pivot point 15 is a threaded rod, and a knob 18 is connected to the rear end with a pin 17, and the threaded portion 16 at the tip is connected to the base rod 4.
By screwing the knob 18 into the actuating body 21, which is housed in a slidable but non-rotating manner, the actuating body 2 is rotated.
1 to slide in the front and back direction.

19 is a ball that allows the knob 18 to rotate freely with respect to the base rod 4 but cannot slide; 20 is a cylindrical body for preventing the ball 19 from coming off.

When the knob 18 is rotated to move the actuating body 21 toward the user's hand, the rear corner portion 22 comes into contact with the rear contact portion 23 of the actuating rod 5 to bring the suture body 6 closer to the needle seat 3.
Finally, the state in which the intracorporeal duct is sandwiched between the suture body 6 and the needle seat 3 can be maintained.

Further, when the actuating body 21 is moved in the distal direction, its front corner 24 comes into contact with the front contact part 25 of the actuating rod 5, and the suture body 6 is separated from the needle seat 3.

Reference numeral 26 denotes a steady resting piece for the operating rod 5, which is inserted into a long groove hole 27 formed in the base rod 4.

28 is a handle fixed to the base rod 4, and 29 is a small hole at the tip of the beak body 1, which is convenient for cleaning the inside of the beak body 1, etc.

In carrying out the present invention, the tip of the beak 1 may be connected to the base rod 4 side with a screw.

Reference numeral 30 indicates an internal body duct such as the rectum, 31 indicates an affected area, 32 indicates a cut portion of the intracorporeal duct, and 33 indicates a sutured portion.

The suturing device of the present invention is as described above, and for example, assuming that the affected part 31 exists near the anus of the rectum, the part of the rectum is pulled out from the anus by inverting the part from the anus to the affected part so that the inner wall of the rectum is outside. , the affected part 31 is pulled out of the body from the anus as shown in FIG.
The superimposed rectum is held between the needle seat 3 and the suture body 6, and while maintaining this state, the rectum on the anal side and the rectum on the inside of the body are connected with the suture needle 11, and both sides of the affected part of the rectum are The procedure involves suturing the rectum, then cutting it, and performing the surgery, or cutting the affected part of the rectum inside the body, protruding both ends outside the body, and suturing it together. By returning the rectum to the body through the anus, it is returned to the body in a sutured state as shown in FIGS. 7 and 8.

The present invention is as described above, and according to the present invention, it is possible to instantaneously suture the entire circumference of the intracorporeal duct.

Further, according to the suturing device of the present invention, since the outer walls of the body ducts are sutured in close contact with each other, the sutured portions are quickly fused after suturing, and a good fused state can be obtained.

In particular, in the present invention, the needle receiving seats for performing the suturing operation of the beak body inserted into the body duct are arranged in a row so as to reach near the corner of the outer peripheral wall surface of the polygonal part of the beak body. However, since one needle seat and adjacent needle seats are close to each other via the corner, the gap between adjacent suture parts can be made extremely small.

In the illustrated embodiment, the needle receiver seats 3 are arranged in two rows in a staggered manner in the longitudinal direction of the base rod 4, that is, the beak body 1, so that in FIGS. seat 3 and the other needle catch seat 3
Although the needle receiver seats 3 are depicted as being separated by some distance, if the needle receiver seats 3 are arranged in a line when carrying out the present invention, one needle receiver seat and the other needle receiver seats 3 adjacent to each other through the corners will be separated. It will be readily understood that the needle seats can be made very close together.

As a result, in the present invention, when suturing a body duct, it is possible to eliminate a gap between a sutured part by one suture needle and a sutured part by an adjacent suturing needle, and the fusion of the sutured parts becomes more rapid. A good adhesion condition can be obtained.

In the present invention, the rear part of the beak body is made into a polygonal shape, and the needle receiving seat is provided on the outer peripheral wall surface of the polygonal part. The affected area can be set in a sutured state simply by inserting the beak body into the body, and the degree of deformation of the body ducts when the beak body is inserted into the body ducts is compared with that when the beak body is flat. In addition, the fulcrum is pivoted on the periphery of a base rod in which a suture body facing a needle catch seat provided on one side of the polygonal shape is extended behind the needle catch seat and behind the beak body. They are attached to the ends of lever-like actuating rods, and moved to the rear of the base rods to push up the rear ends of the actuating rods and sandwich the internal ducts to be sutured between the suture body and the needle seat. By slidably housing the actuating body that is operated to attach the suture body within the base rod, the operation of pinching the intracorporeal duct can be performed very easily and at once, and the operation body that is attached to the suture body can be attached to the suture body. It is also possible to perform a suturing operation by simultaneously operating a large number of pressing bodies, for example, with a small number of pressing bodies, such as one, so in this case, the suturing operation becomes quick, and each pressing body accommodated in one suturing body Since they can all be arranged in parallel, the structure is simple, and the resistance and interference when operating each suppressor is also reduced.

In addition, when implementing the present invention, if the cross-sectional shape of the suppressor is made convex, its strength will be increased.

As explained above, the present invention can reduce the unstitched portion between suture needles as much as possible when suturing body ducts such as the rectum, and also simplify suturing work. It can be performed quickly and has excellent effects during suturing operations in surgery.
